My 90 year old mother is very demanding. I regularly get emotionally exhausted, from her criticisms. She could live many more years (A.L.) to complain, so I wonder if learning to detach would make me less vulnerable. Her phone messages are enough to ruin a whole weekend for me. Sometimes I'm fine for months, but her personality shifts, from docile to aggressive, at a moments notice, (& I never see it coming). Has anyone got tips on detaching, (being less "triggered" by mother's criticisms?) Thank you.
